 		 #98315 - Use Keil or JSIM tools
Responding to: ???'s previous message
Hello Adam,

Calculating machine cycles is one of the easiest things to do. Use Keil performance analyzer window while in the debug mode. Re-zero the counter, set a break point somewhere in your code and run the program. It will stop at the breakpoint then you can go look at the counter to see how long it took the program to run. JSIM.EXE and Raisonance (RIDE) have similar methods. All of these programs are free (Keil demo and RIDE demo) so why not make use of them?

Regards,

Charles Bannister
